Livingbridge-backed Metronet (UK) has appointed Mike Darcey as Chairman.
He was formerly CEO at News UK from 2013 to 2015 following a 15 year stint at BSkyB where he was Head of Strategy and latterly COO. He has also held a number of non-executive Director roles at PA Group and Home Retail Group.
The appointment coincides with a rebrand of Metronet (UK) to M24Seven following the acquisition of Venus in March.
Darcey said: "In the UK, M24Seven has a proprietary wireless network and access to local loop unbundled fibre, particularly in London. This is a differentiated proposition in a crowded market, which is supported by a full suite of business-critical solutions.
"Globally, M24Seven has an IXP network across 16 cities which is only just beginning to be exploited. With so much opportunity, I am looking forward to working with the team to shape the strategy and see what we can achieve together."
CEO Lee Perkins added: "Mike joins the team at an integral point where we bring so much hard work to life, especially our brand. At M24Seven, we believe that that well-connected businesses are more productive and our new brand reflects our ability to support our customers around the clock, enabling them to get more done, 24-seven."
